Car Paint Changes With Temperature
PlayfullyClever writes "It's now common to build materials which can change colors depending on their surrounding environment because of progresses made in colloid chemistry. But now, German researchers have gone a step further. They've used ion bombardment and gold metallisation to produce new particles whose bonding behavior can be chemically tailored. This could lead to new shimmering car finishes which can change with temperature or humidity, new cosmetics, but more importantly, to new applications in optical data processing"
Insightful? Try Bunk
In addition to being ridiculously expensive, it was later decided you couldn't paint your car with it, since it would complicate things if law enforcement needed to locate your car bullshit, they use that paint all the time on cars. you can even buy it in a spraycan now.

Didn't they have similar paint on toy cars in the 80s and 90s?

According to a friend of mine, helicopter mechanic, they already do this to some degree. The gearbox for the tailrotor is painted with a paint which will change colours if it is goes over the maximum allowable temperature. It does not change back to its original colour after cooling down.
This seriously riced out link goes out to all the people who don't know what the parent post was talking about.
This is called thermochromic paint, and it's been available on the market for a while now.
Here's a company that sells thermochromic paint, their website has pictures and even videos of the color changing in effect:

Divide by zero hurts my brain.
As even the summary says, the new part is that it can be turned into different kinds of paint. Unless your car is made of cheap plastic you can't use paint meant for plastic on it.
